Application filed March 29, 1913. Serial No. 757,5

-5 lyn, in the county of Kings and State of New York, have invented anew and Improved ldultiplying Attachment for Cameras, of which thefollowing is a full, clear, and exact description.

This inventionhas special reference to the class of photography and moreparticu- 'larly to improved multiplying attachments for cameras.

:1 be essential object of the invention resides in the production of amultiplying attachment for cameras especially adapted for commercial useand which multiple system of photographing by permitting-one or aplurality of exposures on one plate with a single lens and a singlecamera and one plate holder.

More particularly, the invention resides in the novel arrangement ofswinging or sliding plates in the form or" shutters, for

exposing to view different sections of the plate, and means foroperating said plates whereby one, two, three or four exposures from asingle lens and a single camera may be produced in cooperation with theordi- 4 nary supporting stand for the objects to be photographed, itbeing understood that said I objects will ee-disposed in such relativepositions to conform to the relation of the portions of the camerathrough which light may be admitted.

lVith the above and other objects in view, the invention resides moreparticularly in the peculiar combinations and arrangements of partswhich will be illustrated as a preferred embodiment in the accompanyingdrawings and described in the specification.

Reference is to be had to the accomynmying drawings forming a part ofthis specification, in which like characters of reference in all theviews, and in which Figure l is a rear elevation of a camera having thepreferred form of my improved multiplying attachment applied thereto,certain of the partsbeing shown in section;

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig- 1';Fig. 8 is a vertical longitudinal sectional view of a fragmentaryportion of the camera, the swingn oduces a new ing shutter formingplates being illustrated in dotted lines as when in open position; Fig.at is a side elevation of a fragmentary portion of the camera to moreparticularly illustrate the operating levers for swinging the plates;Fig. 5 is a rear elevation of a camera with a modified form ofmultiplying attachment, a fragmentary portion of the box or frame of thecamera being broken away to show the mounting of the operating memberfor a sliding plate forming the attachment in conjunction with a lightexeluding slide; Fig. 6 is a vertical longitudinal sectional'view of thecamera employ ing the form of attachment shown in Fig. 5,theintermediate portion of the camera being broken away; 7 is horizontalsectional view on the line T-7 in Fig. 5; Fig. is a view similar to Fig.5 but showing a. modified form of attachment, the plate being in anoppositely shifted position; Fig. 9 a face view of a light excludingslide adapted for cooperation with the forms of the attachment shown inFigs. 5 and S; Fig. 10 a fragmentaiy portion of a camera embodying theform of the invention shown in Fig. 1 but with a modified form ofoperating mechanism for the swinging sections or plates; and Fig. 11 isa side elevation of the form of the invention shown in Fig. 10.

In the drawings the numeral 10 designates the frame or box of anordinary commercial or photo-view camera,the same having an internalbead or shoulder 11 to which the usual bellows 12 is attached at theback of the camera, said bellows being also attached to the front wall13 of the camera front or frame section 14 in the usual manner. Thefront wall 13 carries a single lens 15 which is of a type to permitgeneral instantaneous and copying work, whereby when the back section 10is adjusted along the base 16, the proper focus may be obtained toproduce a sharp image.

A plate or negative holder 17 in the form of frame is carried at theback portion of the camera, being held as by means of a pin 18 and aclip 18'. This holder carries the usual closure or hinged door- 19provided with a spring 20 for holding the plate 21 in position andagainst movement in contact with a shoulder 22 produced by rabbetedportions of the holder frame. The holder vided withupper and lowergrooves 23 in which is received the ordinary dark or lightexcludingslide. I

In the preferred form of the invention the holder is as above described,and in addition thereto the head or shoulder 11 beneath its top portionand above its bottom portion carries a pivot rod or shaft 24,journaledat one end in the head as shown at 25, and passed through theback part and head at the opposite side, at which end the shaft carriesan operating lever 26. Fixed to each of the rods 24 is a plate orsection 27, each occupying one-quarter of the space or opening producedby the bead and being preferably of light sheet metal, for instance,aluminium, and adapted to exclude the light from the sensitive plate inits holder.

Mounted on each of the rods 24- is a hollow shaft or tube 28, the samebeing adapted for iinlependent turning or oscillation on the rods orshafts 24 and simultaneously extending through one side of the backsection of the camera frame. Each hollow shaft or tube carries a lever29 and thus the shafts or tubes may be alternately operated to open orclose either one of the sections 27 carried by the rods oinshafts 24 oreither one of the sections 30 carried by the hollow shafts or tubes 28.In this manner onequarter, one-half, three-quarters or all of theopening-may be uneovered to admit lightyand by disposing the objects tobe photographed in the proper relation from one to four exposures may bemade on a single plate with a single lens and a single camera.

The sections 27 and 30 are shown in open position in Fig. of thedrawings, as indicated in dotted lines, but these sections are normallyheld in closed position, and the joints formed at their co-acting edgesare covered to exclude'light by means of strips 31 which terminate atthe inner corners of the sections and which at their outer ends arepivoted to the shafts or rods 24, preferably in contact with the innerextremities of the hollow shafts or tubes 28. Means are provided tonormally hold these strips I'll against the inner faces of the sectionsto similarly hold the latter in closed position, such means consistingof coiled springs 32 engaged on the pivot rods or shafts 24 between theears 33 of the strips, said springs having their opposite extremitiesengaging with the outer faces of the head or shoulder 11 and the innerfaces of the strips, respectively. In order to hold the sections intheir open positions when independently operated as above described, thelovers 26 and 29 are provided with gripping portions having spring pinsor fingers 34 which, when the levers are swung in position to open thesections, will engage with and behind the shoulders or angular catchessecured to the back section 10 of the camera frame and preferably to theoutside of the latter.

As a modified form of operating means for the shutter sections or plates2? and 30, with the parts constructed as d scrihed, as shown in Figs. 10and 11 of the drawings the shafts A and 2S carry pinions 36 which areengageable by rack bars 37 held in contact therewith by springs 38supported from the frame part 10 and hearing on theraclt bars. Levers 3.and 40 are pivoted as shown .at 41 on one side of the section 10 of theframe, and these levers are in .un-a pivotally connected as shown at -12independently to the'raclc bars 37, whereby the shafts 21, and 2s may beindependently turned or oscillated through the respective intermeshedpinions 36 carried by the said shafts. The levers 30 and 40 areengageable with the catches in the usual manner. This form of operatingmechanism is adapted in view of the distant positions of the operatinglevers with respect to the shafts, primarily for cameras wherein theoperating mechanisnrshown in Figs 1, 2 and 3 could not be used at all orcould not be used with convenience.

In the form of the invention shown in Figs. 5, 6 and 7 of the drawings,I provide in lieu of the ordinary dark slide, a slide or plate having alongitudinal or otherwise positioned opening t-l exposing substantiallyon e-half of the negative or printing plate, the same being fitted inthe grooves 23 in the ordinary manner. Cooperating with the plate 433 isaslide or plate 4-5 which is of the same size as one of the sections 27or 30 hcretolj'ore described, and which thus covers one-quarter of thearea of the opening in the frame or baclc section 10. This slide orplate is mounted upon a grooved support 4:6 which is supported on thebottom portion of the bead ll and which is provided at its oppositesides with dwending straps 47 serving to hold it from displacen'ientwhen longitudinally shil'tcd through the instrumcutality of an operatingrod 48 dctachahly connected to the support and pass-ed directly throughone side of the section ll) or through a tubularguide t!) carriedthereby, and having a gripping portion by which it may be manipulated.In this form of the device the parts may be disposed in the positionshown in Fig. 5 so that the lower left hand quarter of the opening isuncovered, or by shifting the slide to the left the lower right handquarter of the opening may he uncovered, and by reversing the dark slide43 to dispose the opening 44 uppermost the upper half of the opeuing maybe uncovered, and in addition to this, should the slide 43 be removedtlh'ce-quarterr-i of the opening will be uncpvere depending upon l,wages the position of the slide 45 as to which lower quarter isuncovered. Both 01'' the slides may also be readily removed, as isapparent to uncover all of the opening.

In the form of the invention shown in Figs. 8 and 9 of the drawings, theslide as has the opening 44 and this slide may be reversed in positionthrough the medium of the usual grasping portion 50, but in lieu of theslide 45 I provide a slide 51 which is mounted. in the same manner butwhich e2:- tends throughout the height of the opening so as to exposeeither upper quarter of the opening in connection With the opening at inthe slide .43 by shifting said slide 51 from one side to the other. Thedotted lines 52 in Fig, 9 of the drawings illustrate in diagrammaticform the relative positions oi the slide .51, and it will be further obvious that by reversing the slide .23 either lower quarter of theopening may be uncovered, and also that by removing the slide s3 eithervertical half of the opening may be uncovered, according to which sidethe slide 51 is shifted,

From the foregoing description in connection with the accompanyingdrawings, will be seen my improved multiplying attachment for camerasnot only results a multiple system oi photographing a novel way, butprovides a structure which in each instance will allow rapid exposurescopying ork, and more essentially, from one to four exposures upon asingle plate With a camera having a single lens Having thus described.my invention, What ll claim as new and desire to secure by Let tersPatent ir-:--
